BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 789,045, dated May 2, 1905.

Application filed January 23, 1904. Serial No. 190,294.

To tZZ 11/77/0711 it 71 0/14 concern.-

Be it known that I, JOHN HENRY MERCER, a citizen of the United States, residing at Cordele, in the county of Dooly and State of Georgia, have invented certain new and useful Improvements in Baling-Presses; and I do declare the following to be a full, clear, and exact description of the invention. such as will enable others, skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful im provements in baling-presses; and the object of the invention is to produce a press of the rebounding type in which provision is made for driving the plunger by means of a rotary post provided with suitable ball-bearings and having arms of different lengths, which are arranged in pairs, one of each pair being adapted to start the plunger and drive the same forward a certain distance, after which a short arm is brought into play to exert a greater pressure as the material being pressed requires greater force.

My invention consists, further, in various details of construction and in combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which Figure 1 is a top plan view of my improved baling-press, showing the sweep and plungerdriving apparatus in position to start the plunger forward, the plunger at its forward movement being shown in dotted lines. Fig. 2 is a similar view showing the second pair of driving-arms in full lines in operative position and in dotted lines in the positions which they assume when the plunger has been partially driven forward. Fig. 3 is a bottom plan view of the plunger-driving member. Fig. 4: is a sectional View vertically through the plunger-driving apparatus, parts of the baling-press being shown in elevation. Fig. 5 is an enlarged top plan View of the sweep. Reference now being had to the details of the drawings by letter, A designates the frame of my improved baling-press, and B the pressboX, which is of the ordinary construction.

D designates the plunger, which is fastened to the plunger-beam E and adapted to have reciprocal movement in the box. The outer end of the plunger-beam is recessed away, as

shown at E, with one side projecting, forming a guard against which one of the arms of the driving mechanism is adapted to contact.

F designates a cross-piece mounted upon the frame of the press, from which rise two pintles Gr and G, upon which are mounted the antifriction-rollers H and between which the plunger-beam has a reciprocating movement. The plunger-beam has one side cut away, as at K, forming an inclined surface and allowing slight lateral movement to the plunger-beam as it is being driven forward.

Mounted upon the upper face of the plungerbeam is an antifriction-roller N, against which an arm of the driving apparatus is adapted to contact in driving the plunger forward.

On the under face of the plunger-beam isa shoulder O, which is adapted to contact with a face of the cross-piece F to limit the outer throw of said plunger, and the spring M has one end fastened to the plunger-beam at M, and its other end is fastened to said crosspiece, the object of the spring being to cause the plunger to rebound when driven forward to its farthest limit.

Rising from the bed-piece of the frame is a post Q, and said post rises centrally through the raceway R, which is grooved upon its upper face and is adapted to carry a series of antifriction-balls R, and a companion raceway T is provided with a groove on its lower face, as seen at T, forming a bearing-surface for the balls upon which the weight of the driving mechanism comes. The shank portion of the bearing member T, which is centrally apertured to receive the post upon which it rotates, has two laterally-projecting arms S, the ends of which are slightly curved in opposite directions, and said arms are diametrically opposite or in alinement with each other. A second series of arms (designated in the drawings by letters W) is provided, each of said arms being recessed, as at W, upon its lower edge, forming a slot to receive the arms S. When the arms WV are placed over the arms S, they are substantially at right angles thereto, and each of said arms W has its inner face slightly convexed toward its plunger-engaging end, as shown. A sweep J is provided, which is fastened at its end in any suitable manner to two of the arms of the plunger-driving apparatus, while a brace J which is fastened to the sweep, is secured at its other end to the other two arms of the plunger-driving mechanism.

The operation of my baling-press is as follows: As the sweep is rotated the arm W comes first in contact with the antifrictionroller mounted upon the top of the plungerbeam adjacent to the outer free end .thereof, and in a further rotary movement of the sweep the plunger-beam is driven forward by the frictional contact of the convexed portion of the plunger-driving arm W, bearingagainst said antifriction-roller, and after the plungerbeam has been driven forward as far as it can be by said arm WV an adjacent arm S of the driving mechanism will contact with the recessed end of the plunger-beam and drive the plunger-beam forward to its farthest limit.-

As the arm S drives the plunger-beam to its farthest forward limit a slight lateral movement will be imparted to the plunger-beam,

and as the edge of the latter comes in contact with the antifriction-roller G the latter will turn and reduce the friction intermediate said arm and the beam, and as the arm S leaves the shouldered end of the beam in the further rotary movement of the sweep the spring which is connected to the plunger-beam will cause the latter to rebound to its normal position, after which the second set of plungerdriving arms will come into play and repeat the operation, thus causing the plunger-beam to be driven forward and returned to its starting position twice at each rotary movement of the sweep.

While I have shown a particular construction of plunger-driving mechanism embodying the features of my invention, it will be understood that I may make alterations, if desired, as to the details of construction of the device without in any way departing from the spirit of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In combination with a press-box and plunger, a spring-actuated beam secured thereto and provided with a shoulder on its under face and having an inclined projection at its free end, a rotary post and support therefor with connections between the latter and said press-box, a cross-piece F upon said support against which said shoulder is adapted to contact to limit the outer throw of the plunger, antifriction-rollers on said cross-piece limiting the lateral throw of the plunger-beam, and an antifriction-roller on the upper face of the plunger-beam, oppositely-extending curved plunger-beam-driving arms upon said post,- a sweep with forked ends secured to said curved arms, the under surface of one of the forked ends of the sweep having a recess terminating at one end in a concaved shoulder, the other arm of the forked end of the sweep projecting beyond the curved arm to which it is secured and having a curved edge designed, as the post is rotated, to contact with said antifriction-roller on the upper surface of the plunger-beam and said curved arms adapted to contact with the end of the plunger-beam, as set forth.

In testimony whereof I hereunto aifix my signature in presence of two witnesses.

JOHN HENRY MERCER.
